The identification and measurement of psychosocial factors that are specific to pregnancy and relevant to gestational weight gain is a challenging task. Given the general lack of availability of pregnancy-specific psychosocial assessment instruments, the aim of this study was to develop a short-form psychosocial assessment tool for the detection of women at risk of excessive gestational weight gain with research and clinical practice applications. A staged scale reduction analysis of the weight-related behaviours questionnaire was conducted amongst a sample of 159 Australian pregnant women participating in the Women and Their Children's Health (WATCH) pregnancy cohort study. Exploratory factor analysis, univariate logistic regression, and item response theory techniques were used to derive the minimum and most predictive questions for inclusion in the short-form assessment tool. Of the total 49 questionnaire items, 11 items, all 4 body image items, n = 4 attitudes towards weight gain, and n = 3 self-efficacy items, were retained as the strongest predictors of excessive gestational weight gain. These within-scale items were highly correlated, exhibiting high item information function value statistics, and were observed to have high probability ( < 0.05) for excessive gestational weight gain, in the univariate analysis. The short-form questionnaire may assist with the development of tailored health promotion interventions to support women psychologically and physiologically to optimise their pregnancy weight gain. Confirmatory factor analysis is now required.
识别和测量与妊娠相关且与妊娠期体重增加有关的特定社会心理因素是一项具有挑战性的任务。鉴于缺乏专门针对妊娠的社会心理评估工具，本研究旨在开发一种简短的社会心理评估工具，用于检测有过度妊娠期体重增加风险的女性，具有研究和临床实践应用价值。在参加 Women and Their Children's Health (WATCH) 妊娠队列研究的 159 名澳大利亚孕妇样本中，对与体重相关的行为问卷进行了分阶段的量表缩减分析。使用探索性因素分析、单变量逻辑回归和项目反应理论技术，从简短的评估工具中得出纳入最小和最具预测性问题的方法。在总共 49 个问卷项目中，有 11 个项目，即所有 4 个身体意象项目、n=4 个对体重增加的态度和 n=3 个自我效能项目，被保留为过度妊娠期体重增加的最强预测因子。这些在范围内的项目高度相关，表现出高项目信息功能值统计数据，并且在单变量分析中观察到对过度妊娠期体重增加具有高概率（<0.05）。简短的问卷可能有助于制定有针对性的健康促进干预措施，从心理和生理上支持女性，以优化她们的妊娠体重增加。现在需要进行验证性因素分析。
